Abstract

L'appareil comporte un passage d'admission principal 12 comportant un venturi 19 de carburateur et un papillon des gaz 13, un passage d'admission supplémentaire 14 raccordant le passage 12, en aval du papillon, à l'atmosphère, une soupape 15 de correction montée dans le passage supplémentaire 14 pour modifier la section de ce passage en fonction des changements de la pression atmosphérique, et des première et seconde soupapes de commande à dépression, 16 et 18, pour commander la section du passage supplémentaire 14 de façon que le débit d'air de ce passage supplémentaire 14 soit proportionnel au débit d'air du passage principal 12. Application aux moteurs de véhicules automobiles.The apparatus comprises a main intake passage 12 comprising a carburetor venturi 19 and a throttle valve 13, an additional intake passage 14 connecting the passage 12, downstream of the butterfly valve, to the atmosphere, a valve 15 of correction mounted in the additional passage 14 to change the section of this passage according to changes in atmospheric pressure, and the first and second vacuum control valves, 16 and 18, to control the section of the additional passage 14 so that the air flow rate of this additional passage 14 is proportional to the air flow rate of the main passage 12. Application to motor vehicle engines.
